Claudication refers to cramplike pains in the calves caused by poor circulation of the blood to the leg muscles. A circulatory system (sometimes cardiovascular system) is an organ system that moves substances to and from cells; it can also help stabilize body temperature and pH (part of homeostasis). ... Human blood smear: a - erythrocytes; b - neutrophil; c - eosinophil; d - lymphocyte. ...

Jaw claudication is pain in the jaw or ear while chewing. The most commonly used application of claudication is to describe the pain in the legs on exertion suffered by arteriopaths. The lack of compliance of the arterial tree, usually due to atherosclerosis, means that on exertion the body is unable to compensate and increase blood flow. This causes severe cramping pain, usually in the calf muscles, which will only be relieved by rest. The jaw is either of the two opposable structures forming, or near the entrance to, the mouth. ... An ear is an organ used by an animal to detect sound waves. ... Chewing is the process by which food is torn and/or crushed by teeth. ...

Spinal claudication is not due to lack of blood supply, but is instead the pain felt on exertion by patients whose leg pain is caused by nerve root compression, usually from a degenerative spine. It may be differentiated from arterial claudication in that it is often only relieved by sitting down, whereas in arterial claudication standing at rest is usually sufficient to relieve the pain.

The ankle-brachial index is a simple, non-invasive test that can be used to assess patients with claudication symptoms. The ankle-brachial index, or ABI, involves obtaining blood pressure measurements in both arms and both legs. The higher of the two arm pressures becomes the denominator, and the individual leg or ankle pressures serve as the numerator in calculating the ABI for each leg. Thus the ABI is a ratio which roughly compares the blood flow in the arms to that in the legs, and can help screen for arterial insufficiency as a source of the claudication symptoms. A normal ABI should be 1.0-1.3, whereas an ABI of less than 0.9 can indicate significant arterial insufficiency. An ABI of less than 0.5-0.6 can correlate with threatened limb loss. An abnormal ABI in correspondence with claudication symptoms usually leads to a more sophisticated imaging work-up to uncover the specific arterial blockages implied by the screening test.

Categories: Diseases | Disease stubs In medicine (vascular surgery), Peripheral artery occlusive disease (PAOD) (also known as Peripheral vascular disease or PVD) is a collator for all disease caused by the obstruction of large peripheral arteries, which can result from atherosclerosis, inflammatory processes leading to stenosis, an embolism or thrombus formation. ...

	Spinal claudication is not due to lack of blood supply, but is instead the pain felt on exertion by patients whose leg pain is caused by nerve root compression, usually from a degenrative spine.
	It may be differentiated from arterial claudication in that it is often only relived by sitting down, whereas in arterial claudication standing at rest is usually sufficient to relieve the pain.

UpToDate Patient information: Claudication (2500 words)
	Claudication occurs because blood flow to the extremities is compromised, resulting in an imbalance between the supply of blood available and the amount needed by the muscles.
	Cramping in the upper two-thirds of the calf is usually due to the narrowing of an artery in the thigh (the superficial femoral artery), whereas cramping in the lower third of the calf is due to disease in the artery behind the knee (the popliteal artery).
	Thigh claudication often results from the narrowing of an artery in the thigh (the common femoral artery), while foot claudication often occurs from narrowing of an artery in the lower part of the leg (the tibial or peroneal artery).
